Africa is the fastest urbanizing continent with more than 40 percent of the population living in urban areas, an amount that is expected to increase to 60 percent by 2050 (World Bank, 2020). Rapid, unplanned urbanization is a major risk factor, leading to an increased concentration of people, inadequate provision of basic services, and infrastructure in exposed areas. Urban areas are particularly vulnerable to flooding, landslides, and coastal impact hazards. Climate change will affect rainfall patterns and temperature, further exacerbating the intensity and frequency of floods. Tropical cyclones bring associated high winds, flooding, and landslides. Climate change is predicted to increase cyclones’ intensity, which can harm cities. Urban informal settlements and slums are extremely vulnerable due to their typically improvised and unregulated infrastructure, dense population, and prevalent poverty , Expected threats to urban areas also include heat waves, vector-borne diseases, decreasing water supply reliability, and sea-level rise, many of which are expected to intensify due to climate change. Many of the rapidly expanding urban areas are coastal and are expected to be particularly negatively affected by severe climatic events over the next 30 to 50 years (World Bank, 2023c).
